`parse_arguments` reads a caller-supplied pointer as a slice

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

`parse_arguments` is safe. It takes `arguments: *const AnyObject` and `argc`, and calls `slice::from_raw_parts(arguments, argc as usize)`. It does not check that `arguments` is non-null and aligned, or that `argc` elements are initialized. Safe Rust can pass a null pointer or a length past the allocation. The maintainer confirmed this on 2026-10-03, including a debug abort on Rust 1.78+ when Ruby calls an arity -1 method (`to_s` via `format`, `puts`, or `Array#join`) with a NULL `argv` and `argc` of 0.
